Si8901B-GS Isolated ADC AC Mains Monitor

The Si8901B-GS of isolated monitoring ADCs are useful as linear signal galvanic isolators, level shifters and/or ground loop eliminators in many applications including power-delivery systems and solar inverters. These devices integrate a 10-bit SAR ADC subsystem, supervisory state machine and isolated UART (Si8900), I2C/SMBus port (Si8901) or SPI Port (Si8902) in a single package. Based on Silicon Labs’ proprietary CMOS isolation technology, ordering options include a choice of 2.5 or 5 kV isolation ratings. All products are safety certified by UL, CSA and VDE (pending). The Si8901B-GS devices offer a typical common-mode transient immunity performance of 45 kV/μs for robust performance in noisy and high-voltage environments. Devices in this family are available in 16-pin SOIC wide-body packages.
